I have files scattered across three or four (or, now that I think about it, possibly five) computers, including three Macs and two Windows...Can I move the files to Lightroom simply by dragging them onto a thumbdrive (flash memory) or onto a CD, and then dragging them into Lightroom? For my main computer, where I have files both in Bridge and IPhoto, can I simply drag them to Lightroom? Or is it more complicated than that? Time to get organized, but I don't want to get involved in a giant c**********.
